Normally, DD comes into work with me "for the morning" (we tend to leave by about 12), and we then used to meet DH in town (my office is 5 minutes from the main shopping street). Head into M&S for any last minute bits and pieces, including DD's birthday cake. Any other necessary shopping (usually all done by then), maybe some cheese or Leonidas chocs might be needed.
We'd then all go for lunch in a coffee shop - coffe, sambo, maybe some cake. And head for home by about 2.30ish.
DH's office now require him to go in on Christmas Eve, and DD wants to continue the new tradition started last year of a Christmas Eve swim in the local yacht club in aid of a homeless charity (there are hot showers there afterwards, and mulled wine, so its not so much of a hardship!). So we will do that rather than town (DH's office is closeby to the club, it's only me in town). So we will probably get lunch locally instead.
Once home, we crack on with the preparations for 25th. Peeling potatoes and veg, making cookies for Santa, DH's annual phonecall to DMIL to remind himself how to cook sausage meat for the stuffing!!
Some cleaning and organizing, maybe some wrapping of presents, and quite likely chatting with neighbours over a glass of wine or maybe getting to sit and watch a movie for a while. DD often disappears up the road to her BFF (or they start thumping around in her room). Quite a relaxed afternoon, generally.
Dinner is a smorgasbord type buffet - lots of different cured meats (parma ham, braseola, spiced beef etc) and salamis, pate, cooked prawns etc. Carrot sticks, cherry tomatoes, olives, hummus. And some nice crusty bread and some crackers. We also open the Christmas cheese board. Everyone picks what they want for themselves.
Then we have the youngest light the Christmas candle and we remember the highs and lows of the year just finishing, and those no longer with us. The Christmas Eve Hamper is produced, with new PJs for all, and lush bath bombs for DD and I as the main items, and her stocking and plastic Santa plate. She lays out her stocking, and the cookies/milk/carrot for Santa and the Reindeer before she goes off for her bath and fresh pjs, comes back down for hot chocolate and then we read "Twas the Night Before Christmas" in bed as the bedtime story.
DH and I enjoy a quiet glass of wine and head to bed relatively early before the chaos of the following day. It's a much deserved quiet and relatively relaxing day after what is usually a manic 6-8 weeks before then between work and other things going on.
